During DNA replication, Okazaki fragments are used to elongate:

  1. A
    The lagging strand towards replication fork
  2. B
    The leading strand away from replication fork
  3. C
    The lagging strand away from the replication fork
  4. D
    The leading strand towards replication fork

Solution & Step-by-step Explanation

DNA synthesis occurs only in the direction. On the lagging strand, synthesis occurs in short, discontinuous segments (Okazaki fragments) that are synthesized in a direction away from the opening replication fork.
